一分钟漏洞结论

影响对象
Red Hat Red Hat Enterprise Linux 10
利用判断
尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。

libsolv是openSUSE开源的一个用于检查软件包依赖的库。 libsolv存在安全漏洞，该漏洞源于解压攻击者控制的压缩数据时输入验证不足，导致堆缓冲区溢出，可能导致信息泄露、程序执行更改或拒绝服务。

Vulnerability Title
Libsolv: heap buffer overflow in libsolv repopagestore via unchecked decompression of malicious .solv page data
来源: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in libsolv. This heap buffer overflow occurs during the decompression of attacker-controlled compressed data within `.solv` files due to insufficient input validation. An attacker can provide a specially crafted `.solv` file, which, when processed by a vulnerable application, can lead to out-of-bounds memory access. This could result in information disclosure, alteration of program execution, or a denial of service.
